Not much of a revelation, just an observation, but how much of sci-fi pushes the ideal that Humanity's path forward is unification?
Star Trek is a major one, and many would state it was a progressive show, and it earnestly was.
It also stated that in its ideal future, there's a Federation of like-minded extraterrestrials, and as a member species, Humanity lives in a united, post-scarcity society under a single government.
To that end, how many alien species in these stories are so inhuman, in that they have no differences, a world-wide government, a single language?
It's laughable how direct the propaganda was, and continues to be.
I disagree. I think they purposefully promote all "good" races as sharing the exact same core values: equality being the top value. This is obvious progressive programming and conditioning.
What's wrong with equality?
Everyone should be treated equally unless they have proven that they are not equal.
